I pulled my '51 Mercury engine out of storage last week in preparation to putting it on my test stand to see if it runs as good as I remember. When I pulled it out, I saw that the crank pulley had a chunk broken out of it. I just missed one on e?ay, so I am wondering ; "Can this be fixed?" Are these cast steel or cast Iron? Could I cut and grind a chunk of metal and weld or braze it in? (I don't have the broken chunk.) Has anyone ever done this? I'm retired, so I have the time, and I kind of like fiddling with stuff like this. Any suggestions or opinions are welcome. I think I may have another one like this in a box somewhere as well.
